I'm in a [potential] pickle here and perhaps SE can give me some good advice on this. These are both IT related jobs.
Ok ~ 1.5 months ago I interviewed at company B which was for a remote position. We had several interviews (on video chat) over the course of a month. It came between me and another candidate. They took the other candidate for the remote position but asked if I was interested in a position which involved relocating. I respectfully declined and asked them to consider me for future positions.
Fast forward I interview at company A. Based on the description I liked it. I only had two interviews and they were both over the phone (one HR one hiring manager). They gave me a really good offer and I accepted. I have never met the team so I am kind of going to this blind. Based on our discussions this company appears very informal and not really "by the book" so I figured this is potentially their style. There are a few red flags such as they never checked my references and I've never been offered a job after only phone interviews but based on my research they are a legit company and my hiring manager seems to be good. I just don't know what I'm getting into, it could all be a lie or it could be awesome!
I am set to start in a week. Now company B comes back to me and says a few other remote opportunities opened up. Company B seemed like a dream job (full time telecommute, my field of interest, and the co-workers seem great since I actually met them over video).
I want to talk to company B about this but I don't know how to go about it. Should I just honestly explain the situation that I have an official start date with another employer but since I really am interested in your company for (insert reasons here)? Explain the fact that the job I was presented may differ from reality due to the suspicions I listed above but I still would like to meet them next week to give them the BOTD? Also explain that I do not want to put an undue burden on the new employer so I would need to know fairly quickly?
What to do?
